“This Guide may be the single most valuable item a novice angler can buy . . . and most of us would do well to re-read the sections on flies, fly selection, and stream tactics every spring before pulling on our waders for the first time.” –Rod & Reel

In Handbook of Hatches teaches how to match the hatch and not worry about identifying the insect until later, if at all, and to fish better, focus on shape, size, and color to choose the best fly for the situation.
